Advanced Molecular Detection and Response to Infectious Disease Outbreaks In 2015, CDC’s AMD initiative continued to revolutionize the response to disease outbreaks by

implementing high-priority programs that improve detection and tracking of infectious pathogens.

Updated: March 2016

CDC scientists used AMD to link a case of

Valley fever from a person in south-central

Washington State to Coccidioides fungus

in soil samples taken in the state, far from

its endemic range in the Southwestern

United States. Investigators later found

additional human and animal cases in the

region. AMD revealed the Washington

strain of this fungus is genetically

different from the strain found in the

Southwestern United States. CDC is using

AMD to better understand the range of

Coccidioides fungus in soil.

In collaboration, CDC and USDA used AMD to examine gene sequence data

of two avian influenza H5 viruses ― H5N8 and H5N2. Hundreds of virus

samples were taken from domestic poultry populations across the U.S.

Results showed that the emerging H5 viruses in poultry were genetically

different from the H5N8 candidate vaccine virus (CVV) developed

during 2014–15. CDC used this genetic data to rapidly create new panel

of H5 CVVs for use by vaccine manufacturers, in case human vaccine

against these emerging H5 viruses becomes necessary.

Washington State AMD Speeds Development of Diagnostic Methods for Zika Virus

When mosquito-borne Zika virus spread to

the Western Hemisphere in 2015, doctors in

Brazil saw increased numbers of babies born

with microcephaly and suspected these were

linked to the virus. Brazilian health officials sent

samples of several Zika virus strains to CDC.

Using AMD methods, CDC scientists were able to sequence genomes of the

viral strains and develop, validate, and distribute a molecular

diagnostic assay protocol to detect emerging strains of the virus within

approximately 3 weeks of receiving Zika-positive samples; a process

that would have required 3‒4 months with older methods.

AMD methods helped trace links between HIV infections associated with

injection drug use in a rural Indiana outbreak. The outbreak affected 190 people, 90%

of whom were co-infected with hepatitis C virus (HCV). CDC also used AMD to

identify the overlap of HCV and HIV transmission

clusters. By combining HIV laboratory data, case

demographic data, and viral genetic sequences for each

infected person’s HIV strain, researchers could monitor

for spread of the outbreak in near real-time, allowing

public health officials to focus prevention efforts,

including outreach for HIV testing and pre-exposure

prophylaxis, where they will be most effective.

Data integration

FY 2016 Priority Areas

CDC completed the first step in developing methods for sequencing DNA of

Mycobacterium tuberculosis directly from sputum. These methods have the

potential to determine the antimicrobial susceptibility of TB bacterium within days

rather than the weeks currently required, leading to earlier initiation of

treatment and decreased spread of antimicrobial-resistant TB.
